profiling clone deletion
by MenTaLguY 20 Mar '05

20 Mar '05

Here are the top three offenders when deleting ~10000 clones: > % cumulative self self total > time seconds seconds calls s/call s/call name > 26.42 35.29 35.29 50000 0.00 0.00 sp_object_get_child_by_repr(SPObject*, Inkscape::XML::Node*) > 14.10 54.12 18.83 9999 0.00 0.00 sp_item_pos_in_parent(SPItem*) > 11.45 69.42 15.30 20003 0.00 0.00 SPSelection::_removeObjectDescendants(SPObject*) They're also the only ones that individually accounted for > 10% of the CPU time, and together these three account for 51% of the entire time. Surprised me, actually; sp_repr_prev() only showed up at 7%, and it was only called 10000 times. So that means my speculations last night were largely wrong. But I guess this is a good illustration (for those following along at home) why it's good to profile rather than assume. ^^; But anyway... pondering how best to optimize things now. Suggestions welcome. I'm a bit reluctant to do the obvious and have every SPObject keep e.g. a hashtable of Node/SPObject mappings for its children, as that would come at a very heavy memory cost. At least for _removeObjectDescendants and sp_object_get_child_by_repr(), we may also be able to call them less in the first place... -mental

Re: [Inkscape-devel] Inkscape SVG Animation Interface
by Jiaxiang 20 Mar '05

It was inspired by Beez Bezier animator: http://beez.sourceforge.net/ I also use Flash 2, but I think it's interface a little annoying (huge buttons) and so are its tools. (I still like it, though.) I just noticed that someone is actually working on an animation extension for Inkscape. It's called Spalah Flash: http://spalah.sourceforge.net/?p=2&m=25&go= Yeah, my mock-up shows the world that I don't know anything about programming. Animation is a complicated task. Oddly, the Beez Bezier animator has even less features than my mock-up, yet it can still produce animation. __________________________________ Do you Yahoo!? Yahoo!

Inkscape SVG Animation Interface

This is just a quick mock-up of an idea for an Inkscape SVG animation interface. http://img42.exs.cx/img42/9633/inkscapeaniui8se.png DISCLAIMER: I'm merely an Inkscape user. I don't know anything about programming or GUI design - and I also don't pretend to know. This is just submitted to give some general idea of what, from the perspective of a this user, may or may not be the bare basics to add such a neat and powerful tool into the Inkscape tool box. Note: This would ideally be an additional window within Inkscape. The genius of its construction/destruction is left to you in the wonderful world of Inkscape development.

"icon preview" comments
by bulia byak 19 Mar '05

19 Mar '05

1. It shows only the last selected object, not the entire selection. So to preview a whole icon made of several objects, i have to group them and select the view. Very inconvenient. 2. There must be some way to set the background color of the dialog. The perception of an icon changes a lot with different backgrounds, and it would be nice to be able to preview different backgrounds in the dialog, without changing the document. 3. Please provide at least the size labels for the buttons. 4. Please make it auto updating on selection changes and modifications, without having to press Update.

Opera 8 native SVG support
by Alan Horkan 18 Mar '05

18 Mar '05

Version 8 of the Opera Web Browser is in beta. http://www.opera.com/linux/changelogs/800b3/ One of the new features is support for SVG 1.1 Tiny, which is what makes this worth posting. With any luck this will serve as a kick in the ass for the Firefox Web Browser and they will also get their act together and support SVG.

Postscript Gradient Export
by Michael Forbes 18 Mar '05

18 Mar '05

Hello Inkscape Developer! I attached a patch for Inkscape to allow it to export both linear and radial gradients subject to all transformations I could think of. I had some problems with GhostView rendering some radial gradients when the focus of the gradient is outside the actual object it fills. But I think it is a bug in GhostScript and not my understanding of PostScript. The only thing I am unsure is whether it is a good idea to change "%!PS-Adobe-2.0" to "%!PS-Adobe-3.0" since PostScript gradients are a Level 3 feature (perhaps some programs can't handle postscript level 3. first time Inkscape hacker, -Michael Forbes ------------------------------------------------------------ Student System Operator binx.mbhs.edu BEN Manager http://ben.mbhs.edu BNC Internet Division http://bnc.mbhs.edu MBHS Webmaster http://www.mbhs.edu BlazerNet President http://blazernet.mbhs.edu Computer Team Co-President http://computerteam.mbhs.edu MBLUG President http://mblug.mbhs.edu ------------------------------------------------------------

That's indeed a problem, and I've been planning to fix it by making the snap distance specifiable in screen pixels, i.e. the same in _visible_ length but different _absolute_ length depending on zoom. I think it would make much more sense. However this would only be possible to do in combination with snapping only to the visible grid lines (some of them become invisible as you zoom out), as I proposed here long ago. I still think it's the best approach, though some people objected (frankly I don't remember their arguments, though I remember not being convinced by them :) and so I shelved this idea. What's the current opinion of people?

reminder for bug reporters
by bulia byak 18 Mar '05

18 Mar '05

Hi all, when reporting bugs in the tracker, please ALWAYS: - indicate the Inkscape version - indicate the platform - ATTACH THE FILE. Even if you think the file is "nothing special" and the bug is obvious. A file's worth a thousand words. It's often difficult to understand the bug explanations; attaching a file helps a lot. More often than not, reported bugs are already fixed in CVS; if you attach your file, a developer can quickly test it and close the report. WIthout the file and with unclear report text, a developer has to waste his time asking questions in the bug (which are not always answered, btw, especially in anonymous reports). So please do us (developers) a favor and always attach the file with your problem. It's much better to attach an unneeded file than to fail to attach a needed one. There are other things you might do to help (such as a backtrace), but a test file is absolutely essential. If Sourceforge won't let you attach a file (happens sometimes), post it on the web somewhere and attach a link in comments to the bug. Thanks!
